To all whom t may concern.:

Be it known that we, RAFAEL RAMos and AMBRosE DE CRDENAS, citizens ofthe Republic of Cuba and of the United States of America, respectively,residing at C0- lonia La Caoba, municipal district of Aguada dePasajeros, Province of Santa Clara, Republic of Cuba, have invented anew and useful Flowing-Machine, of which the following is aspecification.

This invention relates to plowing machines, and its object is to providecertain improvements in the construction thereof so as to give the plowsan efficient resistance to dig into the ground by a secure connectionwith the machine frame, instea-d of being carried behind same withoutpressure as it happens now in the plowingtractors at present lin use.

Another object of this invention is to provide means for cutting theearth in front of the plows, thus aidingl the subsequent work of theplows, and which also serve as gyratory supports for the plows.

A further object of the invention is to provide means for adjusting thedepth at which the earth cutting means and the plows are to work, andalso for raising them at the same time when any obstruction is found onthe ground.

And still a further object of the inventionl is to provide means forraising and lowering at will the plows independently from the earthcutting means, every time that itis required to clean off the earthdeposited thereon and when it may be desired to replace any piecethereof.

The invention is described with reference to the figures of the annexeddrawings, in which:

Figure l is a side elevation of a plowing machine provided with theimprovements which form the subject-matter of this invention.

upon a shaft 3 gyratorily supported on bearings 4 fixed by means ofscrews beneath the sides of chassis 1, and on a pair of steering wheels5 located at the front part of the machine and gyratorily mounted ontrunnions 6 projecting laterally from double-square shape supportingpieces 7 provided with a vertical pivot 8 upon which is rotatorilymounted a sleeve 9 formed at each end of a horizontal cross-bar l0upwardly provided at its central portion with an extension formed by twoparallel lugs, a front one 11 and a rear one 12 leaving between them acavity 13 of concave-arched bottom 13 wherein is lodged the pendingcentral portion 14 of a cross-bar 15 secured by its squarely bent endsand by means of screws upon the inner face of the sides of frame .1, thecentral pending portion 14 presenting a convex arched edge 14" fittingwith the concave arched bottom y13 of cavity 13 in bar 10, and this bar10 is pivotally united with the cross-bar 15 by means of a horizontalheaded pin 16 which is secured in position by means of a forelock 17passing through a hole thereof and which bears against a washer 18mounted on the same pin 16.

On chassis 1 is supported by means of posts 19 a working platform 20 andon the rear part thereof, the rear posts 19 properly enlarged and withother posts 21 hold a shade 22 for protecting the operator against theaction of sunshine and rain.

The tread wheels 2 are operated from a motor 23 supported on the forepart of the platform 20 by means of a transmission mechanism comprisingadriving shaft 24 horizontally arranged intransverse position andgyratorily mounted on journals 25 fixed on platform 20, said drivingshaft 24 presenting a crank 26 through which it connects with theconnecting rod 27 articulated to the piston of an engine 23, and in saiddriving shaft are secured a fl -wheel 28 and a gear wheel 29 meshing witanother gear wheel 30 fixed on al transverse-horizontal shaft 31gyratorily mounted on bearing 32 secured beneath platform 20 and uponwhich is fixed at the side of gear wheel 30 a sprocket'wheell 33connected by means of an endless chain 34 with another sprocket cured bymeans of screws beneath .the sides of chassis 1, said sleeve havingrigidly connected at its end one of the plates 39 of a clutch, thegeared plate 39 of which formspart of the sleeve 40 wedged upon shaft 37and sliding thereon and normally pushed against plate 39 by virtue ofthe elastic action of a helical spring 41 wound up on shaft 37andbearing at one end against sleeve 40 and bearing at the other endaga-inst a collar 42 fixed upon shaft 37, and at each end of shaft outof chassis 1 is fixed a sprocket'wheel 43 which is connected by means ofan endless chain with a sprocket wheel 45 fixed on the rear shaft 3between the chassis 1 and each driving wheel 2. The clutch of shaft 37is operated by means of af hand lever 46 pivoted at its lowerl end on 47upon a bracket 48 secured between two cross-bars 49 and 50 of chassis 1,and said lever is providedwith a catching pawl 51 engaging with a gearsegment 52 xed on the two cross-bars 49 and 50, said lever 46 beingpivotally connected at 53 with a link 54 artlculated with the end oflever 55 connected at 56 with a; fork embracing the sliding sleeve 40 ofthe clutch, said lever 55 being pivoted at 57 on the support 58 fixed tocross-bar 59 of frame 1.

Lever 46 is actuated by the operator from his seat 60 fixed on themiddle of the rear part of platform 20, behind and above a presents at.its ends lugs 67 downwardly directed and which gyratorilysupport-horizontal projecting pins 68 carrying balls 69 provided withvertical trunnions 70 with which pivotally connect the forked ends oflinks 71, which at their other similarly forked ends pivotally connectwith the inwardly extended upper portions of the sup-n porting pieces 7which hold the shafts 6 of front wheels 5. The beveled pinion 64 mesheswith the beveled gear wheel 72 fixed at the end of a longitudinalhorizontal shaft 73 gyratorily mounted on a bearing 74 secured beneaththe cross-bar 59 of frame 1, said shaft 73 being connected by means of aCardan articulation 75 with a longitudinal inclined shaft 76 whichpasses above the platform 20 where it is sup orted on a bearing 77formed in a bracket 7) from the forward edge of the coach-box 61, andsaid shaft 76 bears at its free end a 8 proj ecting fiyheel 79 to beactuated by the operator.

from his seat 60. v

Behind the rear part of frame 1 there are arranged a plurality ofcutting edge disks 80 which are secured on a horizontal cross-shaft 81gyratorily mounted on bearings 82 formed at the end of two longitudinalbars 83 pivotally connected at 84 on the end of two other longitudinalcurved bars 85 mounted by their eye ends 86 on a pivoting shaft 87horizontally mounted across the sides of frame 1, and said curved bars85y are supported at their lowermost end on eyes 88 formed at the lowerend of supportlng arms 89 gyratorily mounted on shaft 3 of the treadwheels 2. The shaft 81 of disks 80 is suspended by its ends projectingtoward the Vsides of the machine and by means of two links 90 and 91articulated together from the ends of two supporting longitudinalinclined bars or beams 92 gyratorily mounted by means of bearings 93secured beneath the same, on the shaft 3 of the tread wheels 2, betweenthe latter and each `sprocket wheel 45. Thus there is formed between thetwo bars 83 and the two bars 92 a supporting frame for shaft 81 of disks80 to enable them to be raised or lowered for adjusting its depth in theground, to which effect it is only necessary to swing the bars 92 uponshaft 3, and this is effected by means of a mechanism consistin insleeves 94 through which are mounte the front ends of said bars 92 andwhich are horizontally pivoted on raised lugs 95 formed at the frontoutwardly bent ends of two levers 96 pivoted at 97 on the inner part ofthe sides of frame 1, these levers 96 being articulated at their otherends with curved links 98 which in turn are pivotally connected at 98with the ends of a horizontal A-shaped frame 99 which is longitudinallyslidablealong guides 100 and 101 fixed on cross-bars 49 and 50, and toone of the branches of the sliding frame 99 is rigidly connected astandard 102 carrying at its upper end a fixed nut`103 which is slidablymounted on a worm-gear 104 arranged in horizontal longitudinal positionand gyratorily supported on a rear standard 105 secured on cross-bar 50and on a vertical supporting plate 106 transversely arranged and fixedat its ends on standards 107 fixed on the sides of frame 1 and in thefront end of said worm-gear 104 is fixed a beveled plnion 108 meshingwith a beveled gear 109 the sleeve of which is loosely mounted on shaft31 and has a plate 110 for engaging with the coupling 111'slidablymounted and `coupled to shaft'37 and which is subjected to the -elasticaction of the' helical spring 112 wound up on said shaft 37 between thecoupling 111 and bearing 32, said coupling 111 being operated by thelever 113 pivotally connected with a fork 113 embracing the coupling,said lever 113v being pivoted at 114 beneath the platform 20 and to thefree end of said lever 113 is pivotally connected an end of the curvedlink 115 which is articulated at its other end to the `hand lever 116pivoted at 117 on a supporting piece 118 fixed by means of screws vtothe inner face of a side of frame 1, the lever 116 being provided with acatching pawl 119l which engages with a geared segment 120 formed at thetop of said supportlng piece v118. By properly actuating the hand lever116, the coupling 111 isr rendered operative or inoperative, thusclutching or unclutching the same with the sleeve of the beveledl gear109, and compelling the shaft 31 to transmit its movement or not totransmit same to the worm-gear 104 for sliding the fixed nut 103 to thefront orto the rear, as might be the case, for lowering'or raisingthedisks 80. In order to give thefshaftj 3,1 oppositegyratoryjmovements, there is Aarrangedbetween same and thedriving shafty24 av drawback mechanism whichy is not illustratedfbecause 4it is notconsidered necessaryand because rsamedoes not` forma partfof thisinvention. y 'With' the object of guiding vthe curved links 98 in theirsliding movement to the front or tothe rear Whic'h'is produced by theirconnection `with the branches of the sliding frame 99, there areprovidedion the shaft 37. peripherally channeled sleeves 121 on whose'channel tit said flinks 98l ontheir lowered' position and with thesam'eobject inviev'vthere are fixed tothe inner facefot' the sides of theframe 1' triangular guiding pieces 122.

On the\Worm-gears 104. and 138 are arranged nuts 147 and 154'Which serveas a butt for the sliding nuts 103 and 137 so as to limit their movementQn said Worm-gears.

There are alsoxed beneath the cross-bar '59 oth-ame 1 square plates 155projecting downward and which serveas a butt to the double army62 et thesteering mechanism in. its backward turningr movement, so' as toprevent' any excessive or undue deviation of the machine. e y y 4 Y fThe operation of this machine is as follows: To move the machine, thehand lever 46 is actuated, once the catching pawl 51 has been disengagedfrom thev geared segment 52, `whereby the coupling 39 attains itscoupling position so that shaft'37 may be actuated fromjthe shaftsi 31and 24, and the tread rWheels 2mayberotated by the intermediate ofthe'sprocket Wheels 43 'and 45 andthe endlesschain 44. The disks 8O dothe Work @Pfk Cutting 'the ground thus ,aiding the fwork bf thjegrates126 which is that of lifting the groundlalreadyjbroken by the disks, at,the saine time that 'the blades 130 divide` the lumps lifted by thegrates 126 and the mold-- boards stir up the lifted ground. The depth"at v'i'vhich the disks 80 and the grates 126 are to 'depends' upon theclass of the groundfand the kind of labor which is to be y ierfo'rmedthereon, and v this' ydepth is gra uated by raising or lowering` tothedesired v'point thev supportingl frame offdisks 80, since theplovvs aremounted on a gyratory` frame ont-he shaft 81 of the disks, and to effectthis, lonce the `catch 119 has beendisengaged {fromfthe gearedl segment120, the hand-lever v116 'is properly actuated, `"Wherebythe couplinglll'at'tains its clutching position and the beveled gear 109 isfrotatedAivith,shaft 31 end through the intermediate of the beveled pinion 108said beveled gear 109 causes the worm-gear 104 to be rotated,

thereby producing the sliding movement of the nut 103 on said worm-gearand carrying along the sliding frameV 99 which by means of the links 98s wings'- the levers 96 on their pivots 97 thus raising or lowering, asthe direction of the movement may be, the forward ends of the supporting-bars 92 which are swinging on shaft 3, whereby are respectively raisedor lowered the rear ends of the same bars 92 which hold the shaft 81 ofdisks 80 together with the longitudinal bars 83 supported at 84. Thesame mode of operation is followed when there is found on the ground anyobstruction that might injure the disks or plows, ,raising these workingpieces by the proper action of the hand lever 116.

Whenever it is desired to raise the plows independently from the disks80, for instance to cleanse off the earth gathered thereon' or forreplacing a grate, knife or mold-board, then the hand lever 149 isproperly actuated, after disengaging the catch 155 from the gearedsegment 152, whereby the coupling 143 attains its clutching position andthe beveled gear 141 is caused to turn with shaft 31 so that it may meshwith the beveled pinion 140 and the worm-gear 138 be rotated, wherebythe nut 137 slides on the latter and carries along with same theinclined frame 135 whose ends are connected to the triangular plates 131that move along the inverted V-shape supporting pieces 123 which rotateat their inner end on shaft 81 of disks 80 and assume the raisedposition shown by dotted lines on Fig. 1 of the drawings. Once thecleansing or repairing operation of the plows has been completed, thesame are lowered again actuating the general draw-back lever of shaft 31and actuating in the manner already described the lever 149.

The supporting construction of the forward part of tthe machine on thefront set of wheels, permits, when turning same in either direction forturning the machine that the latter may not incline itself, particularlyon a sloping ground, owing to the fact that the arched support of theconvex edge 14 on the concave bottom 13 of cavity 13 formed by the bar10 that connects the two front wheels 2, permits the seat 13 to rotatearound the central pivot 16 and to slide itself on the edge 14 of thecentral portion 14 of cross-bar 15 fixed to frame 1, and to keephorizontal the latter.
